On nonbinary quantum convolutional BCH codes
Giuliano G. La Guardia
Abstract
Several new families of nonbinary quantum convolutional Bose-Chaud-huri-Hocquenghem (BCH) codes are constructed in this paper. These code constructions are performed algebraically and not by computation search. The quantum convolutional codes constructed here have parameters better than the ones available in the literature and they have non-catastrophic encoders and encoder inverses. These new families consist of unit-memory as well as multi-memory convolutional stabilizer codes.
